What TTB Library Does in Osclass
TTB Library is the shared Osclass foundation for compatible TTB modules, not a separate marketplace feature that users must buy.
A shared component reduces duplicated admin code
When several plugins need the same control-center functions, shipping separate copies inside every product creates version conflicts and duplicated maintenance. A shared library gives compatible modules one verified place for common discovery and administrator UI helpers.
The library is not the feature plugin itself
Installing TTB Library does not add Google Login, image management, 2FA or another commercial feature on its own. Those capabilities remain in their individual plugins. The library provides common infrastructure used by products that declare the dependency.
Keep the shared component current
When an installed TTB plugin relies on the library, the shared component should remain enabled and current. Removing it while dependent modules are active can remove common UI or helper functions those modules expect.
Why it is free
TTB Library is distributed as a free Core component because its purpose is to support compatible TTB software. Customers pay for the functional products, not for duplicated framework code.
